HashiCorp TERRAFORM-ASSOCIATE-003 Online Questions & Answers

• Question 381:

  Using the terraform state rm command against a resource will destroy it.

  A. True
  B. False
  B. False

  ---

  Explanation

• Question 382:

  How do you specify a module's version when publishing it to the public terraform Module Registry?

  A. Configuration it in the module's Terraform code
  B. Mention it on the module's configuration page on the Terraform Module Registry
  C. The Terraform Module Registry does not support versioning modules
  D. Tag a release in the associated repo
  D. Tag a release in the associated repo

  ---

  Explanation

  This is how you specify a module's version when publishing it to the public Terraform Module Registry, as it uses the tags from your version control system (such as GitHub or GitLab) to identify module versions. You need to use semantic versioning for your tags, such as v1.0.0.

• Question 383:

  Which command lets you experiment with terraform expressions?

  A. Terraform console
  B. Terraform validate
  C. Terraform env
  D. Terraform test
  A. Terraform console

  ---

  Explanation

  This is the command that lets you experiment with Terraform expressions, by providing an interactive console that allows you to evaluate expressions and see their results. You can use this command to test your expressions before using them in your configuration files.

• Question 384:

  If you update the version constraint in your Terraform configuration, Terraform will update your lock file the next time you run terraform Init.

  A. True
  B. False
  A. True

  ---

  Explanation

  If you update the version constraint in your Terraform configuration, Terraform will update your lock file the next time you run terraform init3. This will ensure that you use the same provider versions across different machines and runs.

• Question 385:

  Your configuration file has been locked accidentally. What of the following command would you use to unlock?

  A. terraform filename-unlock
  B. delete the file and create a new state file
  C. terraform force-unlock
  D. state.tf-unlock
  C. terraform force-unlock

  ---

  Explanation

• Question 386:

  Which of the following actions are performed during a terraform init?

  A. Initializes downloaded and/or installed providers
  B. Initializes the backend configuration
  C. Provisions the declared resources in your configuration
  D. Download the declared providers which are supported by HashiCorp
  A. Initializes downloaded and/or installed providers
  B. Initializes the backend configuration
  D. Download the declared providers which are supported by HashiCorp

  ---

  Explanation

  The terraform init command is used to initialize a working directory containing Terraform configuration files. This is the first command that should be run after writing a new Terraform configuration or cloning an existing one from version

  control. It is safe to run this command multiple times.

  This command is always safe to run multiple times, to bring the working directory up to date with changes in the configuration. Though subsequent runs may give errors, this command will never delete your existing configuration or state.

  terraform init command does

  *

  Copy a Source Module

  *

  Backend Initialization

  *

  Child Module Installation

  *

  Plugin Installation https://www.terraform.io/docs/commands/init.html

• Question 387:

  You are writing a child Terraform module that provisions an AWS instance. You want to reference the IP address returned by the child module in the root configuration. You name the instance resource "main'.

  Which of these is the correct way to define the output value?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  A. Option A

  ---

  Explanation

  output "name-rg" { value = azurerm_resource_group.example.name }

  output "name-rg2" { value = "${azurerm_resource_group.example.name}" }

  Changes to Outputs:

  +

  name-rg = "example-resource-group"

  +

  name-rg2 = "example-resource-group"

• Question 388:

  Which command should you run to check if all code in a Terraform configuration that references multiple modules is properly formatted without making changes?

  A. terraform fmt -write-false
  B. terraform fmt -list -recursive
  C. terraform fmt -check -recursive
  D. terraform fmt -check
  C. terraform fmt -check -recursive

  ---

  Explanation

  This command will check if all code in a Terraform configuration that references multiple modules is properly formatted without making changes, and will return a non-zero exit code if any files need formatting. The other commands will either make changes, list the files that need formatting, or not check the modules.

• Question 389:

  When using parent/child modules to deploy infrastructure, how would you export a value from one module to import into another module.

  For example, a module dynamically deploys an application instance or virtual machine, and you need the IP address in another module to configure a related DNS record in order to reach the newly deployed application.

  A. Export the value using terraform export and input the value using terraform input.
  B. Configure the pertinent provider's configuration with a list of possible IP addresses to use.
  C. Configure an output value in the application module in order to use that value for the DNS module.
  D. Preconfigure the IP address as a parameter in the DNS module.
  C. Configure an output value in the application module in order to use that value for the DNS module.

  ---

  Explanation

  Output values are like the return values of a Terraform module, and have several uses:

  *

  A child module can use outputs to expose a subset of its resource attributes to a parent module.

  *

  A root module can use outputs to print certain values in the CLI output after running terraform apply.

  *

  When using remote state, root module outputs can be accessed by other configurations via a terraform_remote_state data source. https://www.terraform.io/docs/configuration/outputs.html

• Question 390:

  You want to define multiple data disks as nested blocks inside the resource block for a virtual machine. What Terraform feature would help you define the blocks using the values in a variable?

  A. Local values
  B. Dynamic blocks
  C. Count arguments
  D. Collection functions
  B. Dynamic blocks

  ---

  Explanation

  Dynamic blocks in Terraform allow you to define multiple nested blocks within a resource based on the values of a variable. This feature is particularly useful for scenarios where the number of nested blocks is not fixed and can change based on variable input.
